Most electonics and electrical requires proper operating voltage to work right..since jumping the car cause a severe fluxuation(change) in this, the battery may need replaced..most batteries fail in exteme cold unless they are chemically sound(good) inside..If you have a charger and can connect it to the car while it sits for a few hours the batterys static charge value must be raised to within its normal range.. if not, replace the battery

Starter wont engage. No clicking. all other electrical seems operational


I would try to jump start it! Sometimes all the rest of the electrical seems ok, but the battery won't have enough juice to activate the starter.

If that fails, i would check your connection from the battery to the starter itself!

Why won't my 2012 Suzuki Grand Vitara start?


ill answer for NO ELECTRICAL POWER :
sure and is easy with any DMM meter, got one? any $20 DMM.
my guess;1
engine will not crank
dash lamps out.
head lights out. dead.
post systems of electrical system , all parts that work and those that dont work, and problem is easy.
cleaned battery terminals.
tried borrowed battery that reads, 12.6vdc ? (charged is 12.6)
2012 that is in warranty car.... ?
my guess on 2012
jumping a car, that is battery jump starting.
a battery can short, and no jump start on earth will start shorted battery in car. but does lay down some big sparks, or burns up cheap walmart cables.
if the car will not crank, say just that, my starter motor will not crank
jump started from live running other car.
if true then make sure headlights work , if they dont work fix that first.
HL must always work, even keys in pocket.
best is to put a fully charged battery in the car, jump starting can cause
surges that can damage sensitive electronic$$$, do jumps as a desperate measure,
with a charged battery,
1: Head lights work, no fix that , use voltmeter
2: cranks robustly.
no , wiggle shifter lever, (on A/T cars the park switch blocks cranking) On M/T the clutch blocks cranking.
with any dMM
measure battery voltage before crank and during.
12.6v good. reseted.
cranking.
0 to 10v bad (weak battery or shorted starter motor)
11 and above good. and must crank, if not , starter is bad.
to prove starter is bad, check voltage at starter solenoid coil wire lug.
it must be at 11v cranking , below 8v it chatters, and fails.
if at 0v cranking this lug that means the Key start line is failing.
A/T switch not closes, or bad ignition switch.

Car won't start. I tried to jump it with my other car and still wont work. It makes the electrical noise of trying but thats it. I suspect is the battery, eventough I change it last year. However, I'm


Hi Carmelogo, It would sure help to know more about your problem. First question is what car is it? Secondly when you say it makes electrical sound, what do you mean? Is the starter motor turning, and if so, is it tuning too slowly or just clicking? If it's any of the those I would suggest cleaning the battery terminals, especially if it fails when jumped. If the terminals are oxidized they will need to be removed from the battery and cleaned or maybe even replaced. If the vehicle then starts with a jump and later fails after taking it for a run replace the battery

My 2005 Amanti was driving fine today. Tonight, my husband put gas in it and now it won't start. The lights are flickering on and off, the cd changer lights are blinking and the display on the screen?...


I do not see what the fuel had to do with this, unless the car was cranked for so long that the battery went down. sometimes you pump diesel and car will run about 1/2 block....

Your description sounds like an electrical based issue. Look for grounds, good connections at the battery....get the battery tested, then go on from there. Sometimes batteries fail quickly, but usually will start with a jump....your car sounds like it is not getting electrical power... (Electrically challenged...)

That's not unusual with electrical parts. They can fail with no symptoms. And your symptoms say it is indeed a bad alternator.

Car will start but cuts out and all electric power has failed


The problem has been successfully completed.
The problem was that the battery fitted by Wal-Mart was not secured to the car, subsequently the negative terminal was touching the body of the car at times, this caused the entire electrical system to shut down and of cause when you moved the battery to fit jump leads the car was okay.
Hope this explanation makes sense.
Thank you for your help, it is nice to know someone is out there.

Regards,
